MG Chemicals 801B Super Contact Cleaner with PPE, 4.4 oz Aerosol

I give it 4 and a half really. One very particular complaint. Longer straw!! I'm trying to get into some tight places were potentiometer like to hide and be little pains in my ass. Product is the best you can get if you know alittle about ppe. Its used in nasa! Nuff said. But It won't spray upside down or sideways half empty so maybe double the length or hell, give me 1 foot and let me decide where to shorten it. Still.. only use this on your vintage amps and stuff, other crap destroys your rubber and plastics.

Stopped a quirky potentiometer from acting up. I also used on some outdoor A/C cords that had tarnished connectors. Does the job. Another thing to have in the toolbox.

Used it in sensitive metrology applications and it helped repair a few meters.

I've used this product on the switches, jacks and potentiometers of all my guitars, amps, studio rack gear and audio equipment...and it works flawlessly. Best part is, its half the price of the product I used to swear by (deoxIT)...and its every bit as good. It has brought back to life a few crackling pots I was convinced I would have to replace. Buy it...nuff said.

It cleaned the scratchy pots on my guitar amp AND fixed the channel switch that stopped working for the most part. Should I never need to buy another contact cleaner, I am reordering this one.

Used it once, and inadvertently sprayed some of the product on plastics surrounding the electronic components. In less than two minutes, it whitened every piece of plastic. Product description says “safe on most plastics”. My guess is that it is probably NOT safe in most plastics. At least this product’s description in French is a riot. Not that it would matter to most people but it is so revealing of the company's QC. "Safe on most plastics" labelled on this product does not translate into “coffre-fort sure la plupart des plasatiques” in French, which literally means “SAFE (like a deposit box) SURE (like safe instead of on) most PLASATICS (can’t even spell plastics correctly)”. Total disgrace for a Canadian company. I will stay away from MG Chemicals in the future.

I used this to clean up switches and IC sockets in recording gear from the mid 1980s, and it is the most effective contact cleaner I have used.

Works great
